The Minnesota Vikings have placed running back Adrian Peterson on injured reserve, the team announced.
Peterson had successful surgery on Thursday to repair the lateral meniscus in his knee. He can now potentially return in December, as early as Week 11, dependent on the success of his rehab. Peterson and offensive lineman Matt Kalil are both on IR, but only one can be designated to return this season.
Peterson was injured in the third quarter of team's 17–14 win over the Green Bay Packers on Sunday night.
Peterson has rushed for only 50 total yards in his first two games, after leading the league with 1,485 running yards last season. He had 19 yards on 12 carries against the Packers before leaving the game with the injury.
Minnesota is last in the NFL in rushing offense through two weeks and is averaging a league-low 1.9 yards per rushing attempt.
